Replaced lock and unlock super with a new fs mutex s_lock.

   Hum, is the lock needed at all? Remount & unfreeze both run with s_umount
held for writing. Thus we already have exclusion between these two calls.
The same seems to hold for ext4 BTW.

Agreed, it's not clear lock_super() is needed at all for ext4 at this
point.

Great. I'll remove the calls for ext3/ext4 when I'll submit the second 
version of the patch.

Thanks for your feedback,

Marco
